The PC Board is an OEM part for Frigidaire refrigerators. As the central "brain" of the refrigerator, it controls all electronic functions and directs operational tasks. The board receives input from sensors and buttons to orchestrate temperature regulation, defrost cycles, lighting, and more.

Causes of a bad PC board can include failure over time due to heat exposure, power surges damaging sensitive electronic chips, or liquid ingress corroding circuitry.

Symptoms of a bad PC board include:

• The refrigerator failing to cool or fluctuating temperatures
• Lights not turning on or functionality issues with buttons/displays
• Abnormal mechanical noises or failure to engage components
